Charlize Theron has opened up about her effortless relationship with Sean Penn. The 38-year-old A Million Ways To Die In The West beauty and the 53-year-old actor and director are rumoured to have begun dating last year and publicly confirmed their relationship during awards season when they attended various events as a couple.  Charlize appears on the cover of the June issue of Vogue, and spoke to the magazine for the first time about her new love.

She revealed: ‘Sean and I have known each other for 18 years. We were just really good friends.  ‘And it’s been slow going because you are aware that you could screw that up and lose it. We had to think about it. But at the end of the day, it was somewhat effortless. It just kind of naturally happened, and before I knew it, I was in something that was making my life better - the people who really love me can see the effect it has had on me.’
